6 Claims.

This invention relates to a display device and one of the primary objects of the invention is to provide a structure giving a striking effect whereby the maximum attention will be attracted by the display. A further primary object of the invention is to provide a structure which may be produced at a very low cost of production and which may be assembled from materials easily obtainable. A still further primary object of the invention is to provide a display affected by the transmission and diffusion of light through parts of the structure without having to employ any moving parts.

An advantage of the invention is found in the fact that the display may be set up at any convenient place so that ordinary daylight may be directed against the back side of the structure whereby a successful operation of the device may be had without necessary resort to artificial light.

These and other objects and advantages will become apparent to those versed in the art in the following description of one particular form of the invention as illustrated by the accompanying drawing, in which I Fig. 1 is a fragmentary front elevation of a device embodying the invention;

Fig. 2, a fragmentary rear elevation, and

Fig. 3, a vertical section on the line 33 in Fig. 1.

Like characters of reference indicate like parts throughout the several views in the drawing.

In the specific embodiment of the invention as herein illustrated and described, a cardboard 10 has a cut-out design here shown as in the form of the name of the inventor, the design comprising the letters thereof each forming a window through the card, such windows defining the shapes of the letters. Immediately behind these various letterwindows hereinafter designate ed by the numeral 11, I mount a cellular material as corrugated paper 12, on the back of which is a flat sheet of cellular material as paper 13 attached to the paper 12 tangentially of the rearmost extending parts of the ridges. The ridges of the corrugations are here shown as extending horizontally across the board 10. The paper 12 is held in position across the rearof the windows 11 by any suitable means such as strips of adhesive paper i l and 15 extending across the top and bottom edges of the paper 13 to lap over therefrom onto the back of the board 10.

Both the papers 12 and 13 are of a translucent nature to permit light to diffuse therethrough. The corrugated paper 12 is preferably of different color than that of the back paper 13. This back passes through the combined sheets along those lines than passes through the other portions. In

'fact a lighter color effect is produced along those 6 lines as seen through the windows 11 and a denser color eifect is produced therebetween, this denser color being somewhat variegated as to intensity. The combined effect is to produce letters of an iridescent or opalescent nature, the varying effect depending upon the angle at which the card is viewed and also upon the intensity of the light striking the paper 13 from the rear.

It is to be seen that as the light passes through the translucent white sheet 13, it is diffused some- Z5 what between the ridges of the sheet 12, and since these ridges afford surfaces positioned at varying angles with the sheet 13, the light is continued at different angles accordingly as well as having to traverse different distances in passing 8,0 entirely through the sheet 12. It is preferable to leave the ends of the sheets 13 and 12 uncovered so that some light may enter from these ends to add to the variance in transmission of 'the light from front to back as viewed through the windows 11. In speaking of light striking the sheet 13 from the rear, it is sufficient to use ordinary daylight but in its absence light from any other suitable source may be employed. The thickness of the card 10 is immaterial although it is preferred that it be sufliciently thick as to be more or less opaque so as to prevent transmission of the light therethrough in order to give a sharp contrast about the edges of the windows defining the design. It is understood of course that the 5; papers 12 and 13 should be of a translucent nature so that light may be transmitted therethrough in a diffusing manner and as above indicated the two sheets 12 and'13 should be of contrasting colors, the darker color being next to the board 99 10 with the lighter color exposed on the rear side. While I have herein shown and described my invention in the one form as now best known to me, it is obvious that structural changes may be made therein without departing from the spirit of 5 the invention and I therefore do not desire to be limited to that precise form beyond the limitations as may be imposed by the following claims.

I claim: 1. A display device comprising a board having 1 a design produced by cut-out windows forming openings therethrough, a corrugated paper back of the windows, and a flat sheet of paper back of the corrugated paper, said two papers being in contact with each other and of difierent colors and translucent in nature.

2. A display device comprising a board having a cut-out design defined by openings through the board, and a pair of sheets of translucentmaterial and of difierent colors back of said openings, the sheet adjacent the board varying in distance from the other sheet whereby light is transmitted unequally through the pair of sheets and openings.

3. A display device comprising an opaque member having windows therethrough, a translucent sheet varying as to contour back of the windows, and a translucent sheet back of the first sheet and lighter in color than the first sheet.

4. In a display device, a light transmittingiand diffusing member having a cellular structure defined by front and back walls translucent in nature, one wall being of different color from the other, whereby light in passing through the structure is variably retarded, and diffused by the walls defining the cells to give a variable color effect.

5. In a display device, a light transmitting and diffusing member comprising a translucent flat sheet of material and a translucent corrugated sheet of material, the flat sheet contacting the said fiat sheet being white and said corrugated sheet being of a color contrasting with the flat sheet.
